With the exception of BPPV, vestibular rehab exercises are designed to promote what?
rotational vertigo, positional vertigo, or recurrent dizziness with nausea and oscillopsia or imbalance
UVL diagnosis characterized by: sudden or gradual onset of hearing loss, severe vertigo, nausea/vomiting. Symptoms plateau in approx. 24 hours, and last 3-4 days. Gradually recovery over 5-7 weeks.
UVL diagnosis characterized by: acute onset of severe rotatory vertigo, spontaneous nystagmus, postural imbalance, nausea/vomiting. Recovery gradual over 48-72 hours, with gradual return of balance over 6 weeks.
fluctuating hearing loss, tinnitus, episodic attacks of vertigo
What is the triad of symptoms associated with Meniere's disease?
UVL diagnosis caused by a decrease in endolymph re-absorption, resulting in an accumulation of fluid in the compartment which leads to rupture, causing paralysis of the vestibular/auditory mechanisms.
salt, water, alcohol, caffeine, nicotine
General dietary restrictions for the treatment of Meniere's disease include the restriction of what (5)?
nerve sheath tumor usually found in the internal auditory canal or cerebellopontine angle
progressive unilateral SNHL
The primary complaint with an acoustic neuroma is the insidious onset of what?
watchful waiting, radiosurgery, surgical removal
What are the three therapeutic options for treating acoustic neuroma?
An opening between the inner and middle ear through the round or oval windows, perilymph leaks into the middle ear space, which causes vestibular symptoms.
one major cause of Bilateral vestibular loss is ototoxicity caused by exposure to what group of antibiotics?
streptomycin, gentamicin, amikacin, tobramycin, netilmicin are all examples of what?
oscillopsia, ataxia, nausea/vomiting, light headedness or episodic vertigo, tinnitus, or inabililty to walk in the dark or read while walking are all signs and symptoms of what?
dysequilibrium, oscillopsia, hearing loss/vertigo
What are three primary symptoms reported by patients with ototoxicity?
patients with BVL are more likely to do what, compared to normal subjects their age or patients with UVL?
Type of test that is used to determine which system a person relies on to maintain balance (vestibular, vision, somatosensory)
Research has shown that patients with BVL are initially more dependent on which system for maintaining standing balance?
Dynamic gait index
Measure used to assess the ability to modify gait during changes in task performance for individuals with balance impairments i.e. BVL.
saccadic, smooth pursuit
In order to compensate for the loss in VOR function, exercises used to treat patients with BVL are used to foster the substitution of what eye movements?
lightheadedness or feeling like you are going to pass out. Generalized weakness/blurred vision.
symptoms that are worse in the AM and better in the PM may indicate which type of vestibular problem (peripheral or central)?
Symptoms that are better in the AM and worse in the PM may indicate which type of vestibular problem (peripheral or central)?
Dizziness handicap inventory
self assessment inventory designed to evaluate physical and emotional factors associated with dizziness and vestibular system disease.
Antihistamines, benzodiazepines, and anticholinergic drugs are all examples of what?
vestibulo-ocular reflexes rely on labyrinthine ___________ to sense head accelerations
Which eye system maintains a target in motion on the fovea while the head remains stationary?
Which component of the VOR is mediated by the SCCs and activated by head movements in any direction?
which component of the VOR is mediated by the otoliths and activated by high frequency head movements when near targets are being viewed?
brainstem and cerebellum
Gaze-evoked vertical nystagmus suggests lesions affecting what areas of the brain?
In peripheral vestibular nystagmus (mixed horizontal-torsional trajectory), the quick phase usually beats _________ the side of the lesion.
vestibular nuclear or cerebellar vermis
Vertical nystagmus is 80% sensitive for what types of lesions?
What is the frequency of the tuning fork that is most commonly used to test for hearing loss?
Which test firsts test air conduction by holding the tuning fork outside the external auditory meatus, then tests bone conduction by holding the tuning fork on the base of the mastoid process?
In a negative Rinne test indicating conductive loss, which would be louder, Air conduction or bone conduction?
Which test places the tuning fork at midline on the forehead, and asks the patient if they can hear the sound equally in both ears or better in one ear?
If a person has a conductive hearing loss on the right side, which side will they perceive the sound in the Weber test?
the ability to conrol the body's center of mass relative to the limits of stability associated with a specific task and to the environment in ahiwhc it is preformed
limit of stability
maximum anterior, posterior and lateral distance from center while maintaining the center of gravity within the base of support.
The limit of stability should be approximately ____ degrees front to back, and ____ degrees side to side.
center of gravity
An imaginary point in space about which the sum of the forces and moments equals zero
